Te all @howl/ it may concern:

Be it known that .weRoBER'T STANFORD and PARKER RAYMOND COLFITT, subjects of the King of Great Britain, and residents of Halifax, Nova Scotia, Canada, have invented a new and improved Signal, of which the following is a full, clear, and exact description.

The invention relates to a flare-up i or pyrotechnic signal designed for marine or other uses, and it resides particularly in the special devices for protectingthe illuminant and dring the same at the time desired, all of which will be fully set forth hereinafter and pointed out in the claims.v f,

Reference is had to the accompanying drawings, showing as an example two embodiments of our invention, in which drawings like chara'cters of reference indicate like parts in the various views, and in which- Flgure 1 1s a'perspective view of the signal Y ready for operation. Fig. 2-is avertical section thereof. Fig. 3 -is a view showing the manner-of starting the operation o f the signal.

Fig. 4 is a section on the line 4 tof Fig. '2. Fig.'5 is a perspective view of a modified form of the invention with parts broken away.

Fig. 6 isa section of saidmodifie'd form, showing the re devices. 'Fig. 7 is a view indicating the manner of operating the signal, and

Fig. 8 is a section on the line 8 8'of Fig. 6.

Referring particularly to Figs. 1 to 4, the

signal comprises amain case a, formed of lead,

block-tin, or other material impervious to air 'and water, but readily combustible. This case a is adapted to be filled with any suitable combustibleilluminant, (indicated at 6,) and within the case a, in the upper part or top thereof,

is a priming-case. c, adapted to be filled with a.

i suitable explosive-for example, ordinary '.case is relatively small, it being intended to' gunpowder-as indicated at d. This primingcontain only sucient explosive to tear open l the top portion of thecase a, thuscausing the ignition of the illuminant b, as will be herein- 'g in the top of the priming-case c, said wires f forming part of an electrical circuit which in addition to the source f mayl also' mclude a switch f2 and various other devices for measuring and controlling the electric fluid. Upon closing the circuit f the platinum or other wire e will be caused to glow and this will ignite the priming charge d, causing the priming charge to4 be exploded and ignite a suitable fuse lt, forming alame communication between the priming charge d and the main case a, this fuse then transmitting the flameto the illuminant b. Simultaneously Ass with this operation the explosion of the priming charge will blow out the bottom of the priming-case c, so as to admit atmospheric air to the illuminant to support the combustion thereof. The illuminant willat once are up, giving the desired signal, the color and intensity of which depend upon the character of the illuminant employed. As the illuminant burns the combustible case a will burn down withthe illuminant, thus avoiding obscuring orhampering the flame of the latter.

If desired, mechanical instead of electrical devices maybe provided for the explosion of the priming charge.` Such anI arrangement is illustrated in Figs. 5 to 8, In this form of ythe invention the maincase o' is formed the same as the case a, before described, except that at its upper portion it is provided with a double cover forming a chamber a2. Below this chamber is located the priming-charnbei` d', filled with the priming charge c, the same as before described. t indicates the fuse for carrying the ame from the priming-chamber to the illuminant-case. The priming charge is exploded by a fuse vl, which passes into the priming-chamber d from the chamber az'of the main case a. Said fuse i isadapted to be lighted by means of a strip or plate 7c of suitable material covered with phosphorus or other substance capable of being ignited by friction. supplying member Zisarranged, this memberv consisting, for example, of emery-clotln to which is attached a string m or other means Over this plate or strip Zr a fritionfor moving the emery-cloth, and said string passing through the walls of the chamber a2 to the exterior of the case. The fuse lies over the friction device Z,' and the parts '11, Z,

IOO

and k are held in snug -contact by va suitably- -ignitingthe fuse a'. As -the fuse burns its flame is propagated in the priming-chamber y-Is d', causing the explosion of the powder therein and bringing about the same operation as that which occurs in connection with the construction shown in Figs. l to 4, as above described.

Various changes in theform, proportions,

and minor details of our invention may be resorted to at will without departing from the spirit and scope thereof. Hence we consider ourselves entitled to all such variations as may lie within the terms of our claims.

Having thus described our invention, we,

'claim as new and desire to secure by Letters Patent- 1. A signal comprising a fusible case case therein containing a priming charge, a fuse leading from the priming to the illuminant charge, and means extending into the destructible case for igniting the Vpriming,

charge toA light the fuse.

` the bottom of said destruetible case and thence to the illuminant charge, and means for ignitlng the priming charge.

containing an illuminant charge, a destructible 3. A signal comprising a case containing an illuminant charge, another case therein eon.

taining a priming charge, a fuse leading from the priming charge to the illuminant charge, an igniter embedded in the priming charge, and an electric circuit of which the said igniter forms a part.4 l

4. A signal comprising a case containing an illuminant charge, and another case therein from-the priming charge to the illuminant charge, insulating-tubes passing through said first-named case to the interior of the secondnamed case, an electric igniter embedded in the priming charge, and electric conductors passing through said tubes and having electrical connection with the said igniter, 'the latter and said conductors forming parts of an electric-circuit.

1n testimony whereof we have signed our names to this speeifieation'in the presence of two lsubscribing witnesses.
